# issue.sh — Gitea 議題的讀取與建立（供 jsc-gitea:wiki-to-issue、html-export 使用）。
|
||
#
|
||
# 為什麼要有這支腳本：建議題要組 JSON、要把標籤名換成標籤 id、要把回應裡的編號與網址挑出來，
|
||
# 全是固定的輸入輸出。交給模型每次自己拼 curl，跳脫字元一錯就把議題內容寫壞，而議題是對外的。
|
||
#
|
||
# 用法:
|
||
# issue.sh labels <owner>/<repo> 列出既有標籤：id<TAB>name
|
||
# issue.sh label-ids <owner>/<repo> <name>[,<name>] 標籤名換成 id（逗號分隔）；有名字對不到就 exit 4
|
||
# issue.sh projects <owner>/<repo> 列出專案看板：id<TAB>title；站台沒有這個 API 就 exit 3
|
||
# issue.sh title <owner>/<repo> <index> 印出議題標題
|
||
# issue.sh body <owner>/<repo> <index> 印出議題正文（markdown）
|
||
# issue.sh labels-of <owner>/<repo> <index> 印出議題目前的標籤名，一行一個
|
||
# issue.sh create <owner>/<repo> <title> <body-file> [--labels <id>[,<id>]] [--milestone <id>]
|
||
# 建立議題。輸出兩行: index=<編號>、url=<議題網址>
|
||
#
|
||
# 環境變數: 同 gitea.sh（GITEA_HOST、GITEA_TOKEN；token 缺或被拒時退回 tea 登入金鑰）。
|
||
# 結束碼: 0=成功 1=API 失敗 2=用法錯誤 3=站台不支援該 API 4=名稱對不到 id
|
||
#
|
||
# 陷阱:
|
||
# - 正文一律用檔案傳進來，內容維持 UTF-8 與真實換行；不要在參數裡塞 \n。
|
||
# - Gitea 1.27 沒有公開的專案看板 API，projects 會 exit 3。呼叫端要據實回報「請手動把議題拖到看板」，
|
||
# 不要假裝已經關聯好——關聯不上跟關聯成功看起來一樣，是最容易被當成完成的一種失敗。
